The Rude Stone Monuments of Ireland (County Sligo and the Island of Achill) was published by W.G. Wood-Martin in 1897. The author described the megalithic tombs around his home in Sligo and on Achill Island in County Mayo. In 1897 William Borlase wrote The Dolmens of Ireland, the first country-wide survey of the country's megalithic tombs.
